This New Zealand calculator compares the running cost of gas and electric cooking. Gas can be cheaper per unit of heat, but piped gas carries a daily fixed charge that often outweighs the saving if gas is only used for cooking. You enter your energy use and prices, including the gas fixed charge, and the tool shows the yearly cost each way, so you can see which is really cheaper for your household.
If you keep piped gas only for cooking, the daily fixed charge usually dominates. If gas also runs hot water or heating, that charge is shared, so this comparison is most useful when cooking is the main gas use. Estimate only.
The calculator costs the same cooking energy two ways. For electric, it multiplies the yearly kWh by your power price. For gas, it multiplies the kWh by your gas price and adds the daily fixed charge across the year. Comparing the totals shows which is cheaper, and seeing the gas fixed charge on its own reveals how much of the gas cost is the standing charge rather than the cooking itself.
For 600 kWh of cooking a year, electric at 28 cents is about $168. Gas at 11 cents is about $66 of energy, but a $1.60 daily fixed charge adds about $584, for roughly $650 a year. Here electric is far cheaper, because the gas standing charge dwarfs the cooking energy.
